CASING FOR ROVING-ZERAME MECHANISM.-

Specification of Letters Patent.

Application filed December 17, 1909. Serial No. 533,510.

To all whom it may concern:

Be it known that we, EDMUND E. BLAKE, of Saco, and WILLIAM H.GoLDsMi-rI-r, Jr., of Biddeford, county of York, State of Maine, bothcitizens of the United States, have invented new and useful Improvementsin Casings for Roving-Frame Mechanism, of which the following is aspecification.

The gears and the driving mechanism. especially that at the head ordriving end of roving frames, have heretofore been more or less exposed,no convenient provision having been made for covering it in. Moreoverwhile a casing had been provided for bobbin shafts it was a matter ofsome difliculty and time to remove it to make repairs and for generalcleaning and operating purposes. -When the gears and driving mechanismare uncovered they collect lint and fly and also are apt to throw oil.They are liable to injury and are liable to injure careless operatives.If covered, however, provision should be made for easy removal of thecover and the covers, etc, should allow for the rise and fall of thebobbin rail.

Our present invention is intended to obviate these difliculties and inits present form it consists in a gear box having a cover; the boxsupported by one end of the bolster rail and adapted to move with it;the cover being easily removable from the box without interfering in anyway with the bearings in which the gears or shafts are carried and yetbeing held firmly in place so as to exclude dirt, etc. The coverpreferably also carries sliding shields which slide with the bolsterrail forming a reciprocating door cooperating with a correspondingshield or apron depending from the station ary roller beam to close inthe mechanism under it.

Our invention will be understood by reference to the drawings in WhichFigure 1 is a front elevation of mechanism embodying our invention, thegears being omitted and the gear box being shown in vertical section ona plane in front of the bolster rail. Fig. 2 is a side elevation of thegearbox, etc, the bolster rail and shield be ing shown in section andone of the bearings being removed, and Fig. 3 a plan.

A is the head of the machine containing the mechanism usually containedtherein and having in addition a guideway or vertical track A on whichruns the rail guide A the whole being counterbalanced by a weight (notshown) connected thereto by a chain a, this chain running over asuitable pulley (not shown) contained in the housing a To the rail guideA is bolted the gear box B containing gears B B and B shown in dottedlines in Fig. 3, mounted 011 shafts C and D.

B in Fig. 1 shows an opening in the rear of the box through whichconnection is made between gear B and the operating mechanism in therear of the box.

The shafts C and D are mounted in bearings C C D D connected to the gearvided by which the bracket is attached to the gear box, and a bolt 6 bywhich the rail is especially attached to the gear box.

The gear box has a cover F which is attached thereto by thebearing-attachingbolts 0 (P which pass through the bearings and into thecover. It will be noted therefore that so far as the mechanism is atpresent described, to remove the cover of the gear box it is onlynecessary to remove these bolts 0 d which pass through it. The cover ofthe gear box then may be lifted off and the gears exposed without manyway interfering with their bearings. The cover F is provided with agroove in which the bolster rail sets when resting 011 the bracket E. Inaddition, however, to the cover F, we provide the stationary rail orroller beam G with what may be termed an apron or stationary shield gbolted thereto at g and we provide the cover F with a bracket h to whichis attached a slide plate H, this slide plate being arranged to rise andfall with the bolster rail, the gear box serving as a means ofconnecting the two and in so doing to slide against the apron g. It hasa close or sliding contact therewith and if thought desirable (thoughthis is not necessary), grooves may be provided to Patented Dec. 2,1913.

receive the edges of the shield H to guide it in its vertical movement.-

In the roving frame for which this structure is particularly intendedcertain mechanism is located below the roller beam G. This mechanism isnot shown in the drawings and is not described as it is' not essentialin its detail to the present invention. By the means heretoforedescribed, however, this mechanism is all inclosed within the shield andapron in such a manner that as the bolster rail together with the gearsB B 13 and shafts C and D referred to, rises and falls in the ordinaryoperation of the machine, the part H also rises and falls, sliding overthe surface of the apron 9, always overlapping such apron and thus neverexposlng any of the mechanism back of it under the roller beam G to thedirt and fly which would otherwise reach it.

This invention while quite simple has proved of great value because ithas made unnecessary a great deal of the cleaning which a roving frameotherwise constantly requires because of the amount of lint, dirt andfly which is always circulating around the machine and which because ofthe rapid movement of the parts is apt to be drawn in against the oilymechanism. The tendency of the neat workman to keep his machine cleantempts him to remove dirt, etc., while the machine is in motion andhence expose himself to accident. The closing up of all this mechanismin such a way as not to interfere with the working of the machine and atthe same time to make it possible to remove the cover and shield bymerely removing the bolts 0 d has proved a great improvement upon anyformer construction of which we have knowledge. The removing of theseparts does not in any way interfere with the operative'part of the ma!-chine, but simply exposes it so thatits oper ation may be watched and ifnecessary then may be shut down and cleaned or othen wise attended to.

lVe have shown our invention as applied to one distinct part of aparticular type of machine, but it is evident that its application isnot necessarily confined to this use.

WVhat we claim as our invention is In a roving frame, in combination, astationary roller beam, a stationary guideway, a rail guide cooperatingwith said guideway, a gear box secured to said guide, a reciprocatingbolster rail secured to said gear box at the opposite side thereof fromsaid guide, gears in said gear box cooperating with said rail, shaftsfor said gears, bearings for said shafts secured to said gear box, acover for said gear box detachably secured to said bearings, and meansfor closing the space between said roller beam and bolster railcomprising a longitudinally extending apron depending from said beam anda shield carried by and detachable with said gear box cover andextending therefr m longitudinally of said rail, said apron and shieldbeing in engagement in all positions of said rail and being slidable onone another in a direction transverse to their length.
